After our sustainability project this week you should understand the slogan Reduce, Reuse, Recycle. Of
the three Reduce is the most important. Why is that so? Minimum 50 words. Use examples from your
week without trash to support your answer. Only nouns and verbs count as words in the word count but
it must in complete sentences. (11 points)
If you had to make your presentation to the judges tomorrow, concerning your healthy ecosystem, what
significant information would you present and why? You must discuss at least 5 main points (11 points)
